1. 15 Twisted Pair Wiring There are different grades or categories of twisted pair cabling Category 5 is the most reliable and widely compatible and is required for Fast Ethernet networks You can buy Category 5 cabling that is pre crimped or you can crimp your own Category 5 cables can be purchased or crimped as either straight through or crossed A Category 5 cable has 8 thin color coded wires inside that run from one end of the cable to the other Only wires 1 2 3 and 6 are used by Ethernet straight through crosso networks In a straight through cable wires 1 2 3 Wire Becomes Wire Becomes and 6 at one end of the cable are also wires 1 2 3 Teg TE and 6 at the other end In a crossed cable the order e gt 6 2 of the wires change from one end to the other wire 1 be comes 3 and 2 becomes 6 and vice versa spring The color code for the 4 wires should be as follows Wire clip on 2 bottom 1 white with an orange stripe Wire 2 orange Wire 3 Pin 1 white with a green stripe Wire 6 green The other four wires have to be connected as follows Wire 4 blue Wire 5 white with a blue stripe Wire7 white with a brown stripe Wire 8 brown Z ly To figure out which wire is wire number 1 hold the cable so that the end of the plastic RJ 45 tip the part that goes into a wall jack first is facing away from you Flip the clip so that the copper side faces up the springy clip will now be pa2. 2 Port model and port 16 on all other switches Each port automati cally detects the speed type and duplex of the cabling attached to it and can operate in either half or full duplex giving possible speeds of 200Mbps 100Mbps 20Mbps or 10Mbps Each switch can be connected to workstations PCs file servers hubs repeaters bridges or other switches Each cable connected to the switch must be a Category 5 UTP network cable with RJ 45 tips and should not exceed 100 meters 328 feet in length Ready to use network cables of vari ous lengths can be purchased at most computer stores See page 15 for more details Connecting Workstations and PCs Workstations and PCs should be connected to the switch with straight through Category 5 network cabling If connecting a computer directly to one of the switch s ports connect one end of the cable into the switch then plug the other end of the cable into the computer s 10Mbps or 100Mbps network adapter Uplinking Connecting to Other Switches and Hubs Each 10 100 Dual Speed Switch has a shared uplink port which sits right next to port 12 or 16 on the switch depending on the model you have for connecting or cascading the switch to other devices This uplink port is shared meaning that when it is in use the port next to it on the switch cn no longer be used Since the uplink port crosses the polarity of your cabling for you there is no need to use any special cables A regular st

6. ations Among the proposed solutions to the dilemma of network speed Fast Ethernet has emerged as the most viable and economical Capable of send ing and receiving data at 100 Mbps megabits per second it is more than fast enough to handle even the most demanding video and other real time applications Although there are a number of different competing Fast Ethernet imple mentations 100BaseTX is by far the most popular Operating on two pairs of Category 5 unshielded twisted pair UTP cabling 100BaseTX supports high speed signaling and is relatively inexpensive Because it uses four wires for data transmission and the same packet format packet length error control and management information as 10BaseT 100BaseTX can be made to communicate with older 10BaseT equipment when routed through a switch This scalability is one of 100BaseTX s major advantages over other forms of Fast Ethernet it allows critical speed dependent network segments to be upgraded to 100BaseTX speeds as needed without rewiring refitting and retraining an entire site Heterogeneous networks can now mix both slow and fast network segments for different users or for different depart ments Publishing R amp D video multimedia or accounting departments can enjoy a 100Mbps pace while other corporate segments can operate at slower and more economic 10Mbps speeds A network without a switch is often called a shared bandwidth network because the net s overall band
7. ch can add 10Mbps hardware to your network wherever you want it Planning Your Network The rules that govern how switches are distributed in Fast Ethernet are slightly different from 10BaseT networking rules Cabling specifications distance limits and other topology rules must be followed in order to avoid network collisions and data loss Here are the most important rules to follow 100BaseTX requires four pair Category 5 UTP EIA 568 Cat 5 cabling The maximum cable length from a node to a repeater switch or hub is 100 meters 328 feet The maximum length for a Category 5 100BaseTX cable between a workstation and a stackable or other shared bandwidth hub is 100 meters 328 feet A single or stacked 100Mbps hub is counted as one repeater in Fast Ethernet rules a 10 100 switch or 10BaseT hub is not counted as a repeater You can install as many switches as you want on the same network given you don t position the switches more than 100 meters 328 feet apart The maximum distance between 2 100Mbps hubs without a switch connected in between is 5 meters 16 4 feet The diagram below shows one possible configuration of a 12 Port Switch in a Fast Ethernet environment if you have an 16 or 24 Port Switch the configura tion remains the same Note that like all Fast Ethernet network hardware the switch requires Category 5 UTP network cabling which is available at most computer stores In this example each w
